Chemical Smell

Often, we do not realize just how important our taste and smell senses are to every day life. We go about our day and do the normal human thing. We sleep, eat, shower, get dressed, go to school, work, etc. What if our sense of taste and smell were taken away? How would it change these every day routines? If there were a house fire while we were sleeping and we could not smell the smoke, what would happen? What if we could not taste or smell the food we were eating? What if we could not smell if our bodies were clean when we showered? As a nurse, what if I could not smell a foul odor in regards to urine or

The parietal lobes are located behind the frontal lobes and in front of theoccipital lobes. They process sensory information such as temperature, pain,taste, and touch. In addition, the processing includes information about numbers, attentiveness to the position of one 's body parts, the space around one 's body, and one 's relationship to this space.

Have you ever hated doing the same thing every day? Marge Piercy is an American novelist, essayist, and poet. Marge Piercy was born March 31, 1936, in Detroit at this time America was in a great depression. Her poems are inspired by her mother who was emotional and imaginative, her mother later died in 1985. In the poem “What’s That Smell in the Kitchen” the author show us the way women are sometimes held in low regards by men through the eyes of a tired housewife who does the same thing every day.

Smell, on the other hand, is the sense that comes from odor molecules attaching to the olfactory nerve. Air carries the odor into the nose. Then odor contacts the olfactory nerves at the top of the nasal passages. The the olfactory nerves send a signal to the olfactory bulb of the brain, and the nerve sends a signal to the front of the brain. The forebrain translates the signals of the odor into a specific smell (Swindle, Mark).

The parts of the brain that are involved in the chemical sense of taste are the parietal lobes. The parietal lobe is behind the

Senses airborne chemical molecules • Related to memories & emotions • Consists of 10 million rods embedded in the olfactory epithelium – responding to different chemicals

Smells connection to emotion was also discussed, it turned out to be molecules with receptor signals capable of triggering memory through the olfactory part of our brain and the hippocampus, the site of memory

The sense of smell is a powerful tool that humans have at their disposal. It can have an impact on one's psychological system. When smell enters the scene receptors in the nose, the signal is sent to the olfactory cortex and some parts of the limbic system. The limbic system is responsible for emotions, so it is possible that the sense of smell can have an impact on one's mental make-up. Aromatherapy can be used to treat patients with depression and anxiety using odors. However, studies involving aromatherapy are limited and these claims are not fully solidified. A study to see if aromatherapy is effective in treating depression would be a case study. Case studies provide more information over a longer period, which will allow for the patient

Smell is one of the five basic human senses. Smell is a powerful sense with many abilities. Smell can alert people to potential dangers. Smell brings variety into the world. In addition to these, smell also has one very special ability. Smell can instantly draw memories out of a person.

Although an individual glomerulus may be activated by several odors, the relative levels of activation of several glomeruli differ between odorants. As the concentration of the odorant increases, more glomeruli are recruited to respond; however, the relative pattern of activation is usually maintained for each odorant. Dr. Wachowiak also showed that there is a topographical map in the olfactory bulb such that odorants belonging to a certain class of molecules tend to activate glomeruli in the same area of the bulb, and this map is consistent across animals. Thus, it is possible to study the response to many odor molecules in a large number of animals and collapse the data across subjects to obtain more statistical power. In conclusion, this is an interesting technique that can be used to understand the detailed mechanisms of first-order olfactory perception in live animals. Dr. Wachowiak hopes to continue this research by conducting psychophysical experiments to determine how well the mice discriminate between odors, using genetically encoded probes of neural activity to selectively image certain populations of glomeruli, and studying further steps of processing within the

Plus, the survivor would even be incapable of feeding himself. A brain injury also impacts a person’s ability to speak accurately. Moreover, the coma survivor will most likely face emotional damage as they will randomly burst out in aggressive moods and forget events that are only three minutes old. In addition to this, once an individual wakes up from a coma, their vision will be altered to a point where they will tend to see doubled objects and severe blurriness. On top of all this, a person will constantly feel exhausted and restless. Hence, the coma survivor will feel very weak. A person’s hearing perspective also changes, as they become sensitive to loud or high-pitched noises and can experience persistent ringing noises in ears. Furthermore, a coma survivor will encounter a drastic loss in their capacity to smell as well, some will even lose their smell completely; this is called Anosmia. As most know, smell and taste are strongly related, thus, impacting a coma survivor’s taste buds; causing them to have a bad taste in their mouth and taste food differently.

The tongue, soft palate, and epiglottis are covered with structures known as taste buds, or lingual papillae, that allow humans to sense different tastes in the foods they eat. They are chemoreceptors, meaning that they transduce, or translate, chemical signals in food into electrical signals in the body. These electrical signals, called action potentials, travel to the brain via the nervous system, allowing us to experience the sensation of taste. Taste buds are known as direct chemoreceptors, meaning that they must make direct contact with the chemicals in food in order for us to taste. Distance chemoreceptors, on the other hand, such as those that sense smells, do not need to make direct contact with chemicals.

The thalamus is similar to a doctor that diagnoses, or identifies, a patient's disease or sickness. It diagnoses different sensory information that is being transmitted to the brain including auditory (relating to hearing or sound), visual, tactile (relating to touch), and gustatory (relating to taste) signals. After that, it directs the sensory information to the different parts and lobes of the cortex. If this part of the brain is damaged, all sensory information would not be processed and sensory confusion would result.

The shape is cuticle-covered appendages that contain approximately 120 and 1200 olfactory receptors neurons (Wellerdieck et al., 1997; Zhao et al., 1998).

The question lies does environmental contamination have a major effect on real estate properties? Well environmental contamination turns out can cost the owner of the property or a potential buyer. Environmental contamination on a property may have some implication on the on the property value. Not only could potentially hurt the owner or potential buyer financially it could also do physical damage to the property as well.
